Kenneth Graunke a588cda75a iris: Add a BO_ALLOC_SMEM flag for allocating from system memory
Most allocations will want to be in device local memory (if it exists),
so we default to LMEM in the absence of a flag.  However, some buffers
are expected to be read/written from the CPU multiple times, and we may
want to explicitly place those buffers in system memory.

This patch adds the infrastructure for deciding on the allocation,
and sets the flags, but does not actually hook up the flag to do
anything, as the kernel infrastructure for LMEM support hasn't landed.

Source
------

This repository lives at https://gitlab.freedesktop.org/mesa/mesa.
Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support
-------

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.net/dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
<https://dri.freedesktop.org/wiki/WhosWho/>`_.

The next best option is to ask your question in an email to the
